Description
FIELD OF THE INVENTION

The present invention relates to box springs for bedding, and more particularly, relates to corner members suitable for use on box springs.

BACKGROUND OF THE INVENTION

Mattresses and box springs have been known in the art for many years. Typically, the arrangement is such that the mattress is utilized to directly support one or more people, with a box spring being in position underneath the mattress and above a supporting frame or the like. The box spring provides additional cushioning and supports the mattress and will typically include a variety of springs within its interior.

In the manufacture of box springs, the outside is covered with a fabric material. Along the sides and ends of the box spring, the fabric material may easily be stretched and held in place without problem. However, on the corners, there is a tendency for the fabric to give either inwardly or outwardly when the box spring is in use. In order to overcome this, many manufacturers provide a stuffing of a material such as scrap fiber material at the corners.

A further problem at the corner of box springs and the like is that different sizes are utilized and thus a single piece of material is not suitable.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a corner guard for box springs or the like and which corner guard is adjustable for different sizes.

It is a further object of the present invention to provide a corner guard for box springs or the like and which corner guard has means for securing a fabric adjacent thereto.

It is a still further object of the present invention to provide a corner guard for box springs or the like and wherein the corner has provision for receiving extra material.

According to one embodiment of the present invention, there is provided, a corner guard arrangement for a box spring, the corner guard arrangement comprising a first member formed of a sheet material, a first end of the first member having attachment means for securing the member to a wire of the box spring, a second member formed of a sheet material, and first end of the second member having second attachment means for securing the member to a wire of the box spring, the first and second members each having interlocking means, the interlocking means being arranged to maintain the first and second members together when in an assembled condition while permitting sliding movement of the first and second members with respect to each other, the arrangement being such that when the first and second members are assembled, the first end of the first member and the second end of the second member can be secured to top and bottom wires respectively of the box spring.

According to a further aspect of the present invention, in a box spring having a plurality of wires forming a plurality of coils, with an outer perimeter wire extending about the top and bottom thereof, the improvement comprising a corner guard, the corner guard comprising a first member formed of a sheet material, a first end of the first member being secured to an upper perimeter wire of the box spring, a second member formed of sheet material, a second end of the second member being secured to a lower perimeter wire of said box spring, the first and second members being interlocked together, the interlocking means permitting sliding movement of the first and second members with respect to each other.

According to a further aspect of the present invention, there is provided a corner guard for a box spring, the corner guard comprising a first member formed of a sheet material, a first end of the first member having attachment means for securing the member to a wire of the box spring, the first member being formed to have an arcuate configuration wherein that arcuate configuration has a radius which is larger than a radius of a box spring corner, the attachment means for securing the member comprising a plurality of retaining members extending outwardly from the first end of the first member, each of the retaining members comprising an outwardly extending portion and a downwardly extending portion defining, with the first member a U-shaped recess and at least one pointed member located on the outwardly extending portion to engage a fabric placed on the box spring.

In a still further aspect of the present invention, there is provided a guard member for a box spring, the guard member comprising a first member formed of a sheet material, a first end of the first member having attachment means for securing the member to a wire of the box spring, the attachment means comprising a plurality of retaining members extending outwardly from the first end of the first member, each of the retaining members comprising an outwardly extending portion and a downwardly extending portion defining, together with the first member, a converted U-shaped recess, the first member having an arcuate configuration with a radius which is larger than a radius of a box spring corner and the first member having an aperture centrally located on the first member.

The corner guard arrangement, as set forth above, comprises first and second members which are formed of a sheet material and preferably of a plastic sheet material, many of which are well known to those skilled in the art. Each of the members is preferably formed to have a body portion which is arcuate in configuration, but has a greater radius than the radius of a box spring corner. In so doing, the member will exert a slight outward force when it is placed in position on the box spring corner.

The two members are interlocked in a relationship which permits sliding movement therebetween. Accordingly, the device can be adjusted for different sizes of box springs.

In one embodiment of the present invention, the corner guard includes upwardly extending relatively pointed members for retaining a fabric material which is placed thereover. While normally the corner guard will be placed on the exterior of the box spring, it can also be placed on the interior thereof for retaining the material. If desired, an additional corner guard could be placed on the exterior.

In a still further embodiment of the present invention, the corner guard may include downwardly extending relatively pointed members for retaining a fabric material which is placed thereon.

In a still further arrangement, the corner guard could include both downwardly and upwardly extending relatively pointed members for retaining a fabric material below the corner guard and a further fabric material placed over the corner guard.

In a still further aspect of the present invention, a corner guard is provided with a centrally located aperture, which centrally located aperture is suitable for receiving excess material such that a smooth arcuate appearance is maintained.
